I am considering doing an AA treatment to (hopefully) remove some of the staining on my plaster pool. I am still trying to grasp an understanding of the process, but from my reading so far it appears that an AA treatment removes metals from plaster and suspends them in water via a sequesterant. Am I correct in thinking that these metals are not really removed by normal filtration? You have to keep adding sequesterant to keep them from redepositing on the plaster? Or until you drain the pool? How often would sequesterant need to be added to keep metals in solution? To me at least, it seems like we should be able to come up with a better solution...
I think that the metal staining in my pool is from the Carribean Clear system that was used by the previous owner for around twenty years. From what I can determined, the water has never been changed. I'm not crazy about draining the pool because a) I have a well and b) I have a well. a) refilling my pool would put a large demand on my well and I am unsure of the well's ability to meet that demand and b) I don't exactly have warm and fuzzy feelings about emptying 15,200 gallons of chlorinated water containing metals into my yard as I don't know what effect this would have on my groundwater.
So...
Since the chlorine level for an AA treatment is supposed to be 0 anyway, would some kind of carbon filtration be effective at removing metals suspended in the water? If so how much carbon would be needed and with what kind of exposure time? Would the type of sequesterant make a significant difference in how the carbon removes the metals from the water?
